Description

Aggregations have been implemented in CASSANDRA-4914.

All calculation is performed on the coordinator. This means, that all data is pulled by the coordinator and processed there.

This ticket's about to distribute aggregates to make them more efficient. Currently some related tickets (esp. CASSANDRA-8099) are currently in progress - we should wait for them to land before talking about implementation.

Another playgrounds (not covered by this ticket), that might be related is about distributed filtering.
